如何在rspec中打印let符號的值？在我的規格

Question

如果我有以下行

include Rack::Test::Methods 

    let(:competition_date) { Date.today+10.days } 

如何打印competition_date符號的RSpec的價值？

Answer 1

在RSpec中，在let中定義的變量可在before和it塊中訪問。全部必須包含在describe區塊內，但是，如：

describe "let variables" do 
    let(:competition_date) { Date.today+10.days } 
    it "should be accessible within it blocks" do 
    expect(competition_date).to be == Date.today+10.days 
    puts competition_date 
    end 
end
